Writing register: # echo value > /sys/path/to/file Reading register: # cat /sys/path/to/file Also, since your FPGA is in development phase I assume that the registers base address is changing (or am I wrong?). You can solve this with an additional writable sysfs entry which will hold the current base address. thanks, Daniel. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
